Url rewriting problem

[eluser]Unknown[/eluser]
Hello , i have a little problem on url rewriting.

my defautl .htaccess file was like this

Code:

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

so for example to access to a contact file i used to do http://site.com/en/contact/

now what i want to do is to access to the contact page using some hebrew caracters like

http://site.com/en/לבנות


so my new .htaccess file is like that :

Code:

RewriteEngine on
RewriteRule en/לבנות$ index.php?/en/contact

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

But this isnt working i dont know why it give a 404 not found page can someone please help me.
thank you.
